A further object consists of fastening the contacting surface of the' bracket in order that it will be self-adapting to awidefrange of pole diameters and of the various materials, such as steel and wooden poles. j

The accompanying vdravvingsillustrate a preferred form and amodication of the invention and are incorporated into4 the speciiication.

Figure 1 is an elevational front View of the bracket together with its adjustable members and a three light lamp casefsupported thereon, the back ground shield being broken away to clear the View of major parts of the'. bracket. Fig. 2`

is a side elevation of Fig. 1. Fig. 3 is'ra cross-sec- Y tional view of the bracket in Fig. 2 along the line y 3, 3. Fig. 4 is a modifiedform of Fig. 3. Fig. 5 is a fragmentary elevation of a poletop mounting. y

In the drawings,l 10 represents light' cases y which are mounted in tier formation upon bracket 11 whichcan be attached to poles either by U bolts as shown by'l2 in dotted lines of Fig. 3, or through bolts indicated by 13, which are preferably used for relatively large diameter poles. Bracket l1 is formed with a vertical back member 11a `and horizontal projecting member 11b which terminates in apreferably round perch llc through the lcenter ofA which passes a bolt hole for receiving bolt 14. Onthis perch is disposed a plate 15v to' which is articulated an upper I leaf 16 at bearing 17 thus forming a hinge, 15 being the dead leaf and 16 the movable leaf. Screw stud 18 is secured, preferably fused, into leaf 16 and` passes through an elongated slot of the lower which' aretsenured "to ieaff i6 along with Samet es iredffseleted adjustment v. a railing` practically ;Within ahlen? msi-:weie

The laterally projecting lugsllg are fashioned .Y with perforated elongated'slots toaccommodate the U bolts of varying dimensions; which may be which the installation is to be made.

It will be noted that means are provided for eiecting solid contactswith poles of varying d-Yy j ameter with the use of a single bracket, thus dis-` pensing with the use of the customary adapters heretofore employed by the manufacturer. The benefit derived from this type of bracket extends to the service men and relieves them'of the ne#` cessity of carrying a stock of brackets of varying proportions and/ or improvising make shift .40 blocksand supports to effect the neces rydependable installation.

I claim:- o n 1. In combination, a supporting.po1e', and a bracket fashioned with a verticalback fromy .l

whichv extend lateral projecting arms with perfe central portier- 1 d forated slots and disposed in substantially the same plane; the rear surface of said back and arms being fashioned with one set of angularly ydisposed lugs developed by adjacent depressions and another set of angularly disposed lugs developed by projections; said lugs being so disposed that only one set will contact with a pole of greater or lesser diameter than one of a critical diameter.

2.
